About us

VENTS GROUP Sp. z o.o. is a well-established company in the ventilation industry. At its inception, as Domus Ducting Polska Sp. z o.o., it was one of the few pioneers introducing mechanical ventilation systems to the Polish market. Following new trends and building customer awareness in the industry, the company has expanded its offer over the years to include heat recovery (HRV) solutions. Today, it offers a comprehensive range of products from ventilation grilles to modular air-handling units. This wide assortment is backed by the powerful resources of the international BLAUBERG Group with its seven production plants in Europe, of which Vents Group is a part.

As a company, we offer comprehensive ventilation and heat recovery solutions.
Strengths: a wide portfolio, equipment availability, technical support, “Czyste powietrze” program (ZUM).
